Sensors according to EN 60947-5-6 (NAMUR)

or potential-free contacts can be connected

to the IMX12-DI03-1S-1NAM1R-PR/24VDC

NAMUR repeater The device is equipped with

an intrinsically safe input circuit and can be installed in zone 2. The output circuit is additionally equipped with 1 relay output. The device

can be powered from a power bridge that also

transmits a collective fault signal. The device

complies with the requirements of the NE21.

The devices feature DIP switches on the front.

Thus, the direction of action and the input circuit monitoring can be switched separately.

When using mechanical contacts, either line

monitoring must be switched off or the contact

must be wired with resistors (see wiring diagram).

The Pwr LED lights green to indicate operational readiness. An error in the input circuit leads to a flashing red LED according to

NE44. A LOW level is then emitted at both

outputs and the common alarm output becomes conducting.

The device can be used in safety circuits up to

SIL2 (high and low demand according to IEC

61508).

The device is equipped with removable screw

terminals.
